Плохое качество и проблемы с воспроизведением видео при использовании VLC

Я сталкиваюсь с проблемами при воспроизведении видео в кодировке H.264 (не проверено с другими) с VLC или другими проигрывателями (проверено MPlayer, Totem не воспроизводит видео только звук). Я уверен, что это о водителе, но я не знаю, как это исправить. Я пытался установить проприетарные драйверы от AMD, но после перезагрузки я не могу войти (только Терминал). Моя видеокарта - серия AMD Radeon HD 8. Я не знаю, связано ли это, я загружаю с параметром nomodeset. Спасибо за вашу помощь.
